Course at a Glance : Introductory course for Electronics.

Pre-requisites: Electric Circuits

Common Sense ( Dimaagh )

Important because more youll study more courses in the upcoming semesters that would require the knowledge you attain during this semester.

And because you might be asked questions related to electronics when you appear for a job interview =)

One of the most fun, and most interesting courses.. OK, OK, just my opinion.

Apart from Coursework

Apart from coursework, you are also expected to: Enhance your technical skills.

Demonstrate appropriate social skills by team work.

Exhibit self esteem by showing confidence in your abilities.

Display integrity and honesty.

Participate actively in co and extra-curricular activities.

Overall, just being a better person than you already are.

Feedback will be provided on request.

misbah@uet.edu.pk For:

Submitting the online assignments

Asking a sensible question

NO SPAMMING

Write your name , roll number and subject in every email.

Writing an email (general):

Start with a greeting, End in regards

Write an informing subject of the email and

your name at the end of the email.

Dont use any slang or short text forms, be polite but firm.

Lecture slides will be uploaded to:

Attendance

Does not count for any marks.

You are expected to stay quiet during the lecture unless asked a question, or to ask one.

Slides alone dont cover everything. You are expected to take notes during class, and read from the suggested books afterwards.

You are encouraged to ask questions during or after the lectures, anytime.

Cheating/Plagiarism Policy

You are allowed to cheat. But you must also be sharp enough to dodge the invigilator.

Any copied assignments will be given negative marks without notification.

Anyone caught cheating during evaluations will immediately be thrown out of the examination room.

Also remember Cheating karnay wala, aur Cheating karwanay wala, dono barabar hain =)

Miscellaneous

Major assignments and projects can be resubmitted within the given time. There will be 10% reduction in grading.

You are allowed to bring something to eat or drink during the lectures except : All kinds of chips =/

If I find excess noise, or any wrappers on the ground after or during the lecture, there will be consequences.

The Question Mark Guy:

Usually means trouble: i.e. a question asked by me, to you or worse, an assignment

My Pledge to You

I will trust you until you give me a reason to do otherwise.

I will respect you and work with you to solve problems.

I will promptly correct and offer feedback on your work.

I will work with you to meet learning goals.

I will offer extra help and alternative assessments should you require them.

ELECTRONIC DEVICES AND CIRCUITS

Introduction

What is:

Electronics? Electronic Devices? Circuits?

Electronics means study of flow of electrons in electrical circuits.

The word Electronics comes from electron mechanics which means learning the way how an electron behaves

Electronics

under different conditions of externally applied fields.

An electronic building block packaged in a discrete form with two or more connecting leads or metallic pads.

Components are connected together to create an electronic circuit with a particular function.

E.g.: an amplifier, radio receiver, or oscillator.

Electronic Devices

An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.

Circuits

Building electronics

Started with tubes, then miniature tubes

Transistors, then miniature Transistors Bardeen, Brattain, and

Shockley invent the first germanium point contact transistor at Bell Labs in 1947 (they received a Nobel prize for this discovery).

Early Electronic Devices

ENIAC (Electrical Numerical Integrator And Calculator) Developed by Mauchly and

Eckert in 1946

17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1500 relays, 6000 manual switches, and 5 million solder joints; covered 1800 sq. feet of floor space; weighed 30 tons; consumed 160kW.

Built to calculate ballistic trajectories (ballistic firing tables).

Big Electronic Computers

Then along came the Integrated Circuit (IC)

Invented by Jack Kilby of Texas Instruments in 1958 (received a Nobel Prize in Physics 2000)

Beginning of Modern Devices

The IC industry has been able to continue to reduce the size of transistors and increase the number of devices that can be integrated onto a single device.

Modern ICs

Moores Law
